           What is Technology?

    According to one dictionary:
    • The study, development, and application
      of devices, machines, and techniques for
      manufacturing and productive processes
    • A method or methodology that applies
      technical knowledge or tools.

              What is Technology?

    • According to Michael Patrick “ Technology is
      the practical application of knowledge
      gained through theoretical research to
      specific production problem”.
    • According to Alan Paau “Technology =
      knowledge to do something”
    • According to Andrew Grove “Technology
      drives change”.

           What is Internet ? (Conti.)

     According to John Perry Barlow “The
     Internet is too widespread to be easily
     dominated by any single government. By
     creating a seamless global-economic zone,
     anti-sovereign and unregulatable, the
     Internet calls into question the very idea of
     the nation-state”.

         Technology in the recent wars

     • German submarine “Wolf Packs” proved to
       be an important force during WWI.
     • During WWII, a brilliant Polish cryptanalyst
       named Rejewski figured out how the
       German Enigma machines worked and
       shared this with the Allies. Recovered code
       books revealed that weather information
       was being used as encryption keys.

      Technology in the recent wars (Cont.)

     • With this intelligence, code-breakers at
       Bletchley Park in England were able to
       break the German codes. This meant that
       the Allied convoys could avoid the German
       subs and many subs were sunk. This was a
       turning point in the war.
     • US used precision guided munitions in the
       Gulf war in 1991 and Iraq war in 2003
